Of course Trump didn't give a damn regarding the safety of others.
"Trump Didn’t Even Try to Keep His Own People Safe The president apparently took no measures to protect his political advisers, aides, and donors, and largely left them in the dark once he had tested positive."
What else would anybody who knows Trump expect?
"What does still shock is the recklessness with which Trump treated the health and lives of those closest to him. Despite being potentially exposed to a virus he described in February as “deadly stuff,” the president apparently took no measures to protect his political advisers, aides, and donors, and largely left them in the dark once he had tested positive."
Why would it shock anyone? It shouldn't.
We overanalyze Trump. He is what he appears to be.
There is no correct Theory of Trump.

But what if there’s nothing to understand? What if there’s no there there? What if our attempts to explain Trump have failed not because we haven’t hit on the right one, but because we are, theory-of-mind-wise, overinterpreting the text?
In short, what if Trump is exactly as he appears: a hopeless narcissist with the attention span of a fruit fly, unable to maintain consistent beliefs or commitments from moment to moment, acting on base instinct, entirely situationally, to bolster his terrifyingly fragile ego.
